No need for midi in and midi out. I don't want to plug anything midi related to the sound card. I just want it to have the ability to play midi plays with a quality soundfont.

I remember trying Ultima 7 port (Exult) on my Amiga maybe around year 2000. It had midi support but it slowed down everything too much. If there was a way for the soundcard to play midi without using much of the cpu time, that would have been great.

That would work for the later midi games, for SC and General midi, but MT32 relies on Sysex transfers to alter the sound fonts. Doom, Heretic etc would be ideal for this type of sound card, but not Monkey Island and the many other MT32 games.
Saying that, I would buy such a card
